t IMPROVEMENT IN MACHINERY FOR DRESSING- SKINS'.

The Schedule referred to in these Letters Patent and making pari: of the same.

accompanies and forms part of 4this-specilieation, is

a description of our invention' sufficient t-O enable those skilled in the art to practice it.

Our -invention vrelates to an improved means of brushing, coloring, and polishing` skins, in the manu.- facture of leather; and Our improvement consists in. combining with'a table or beam, mountednpon asuitable frame, andin :in inclined position, and resting'upon springs which permit it to yield verticallyg'a cylindrical and rotary brush, whose-axis is parallel to the beam, and whose bristles rotate in contact with the beam, the skin to be treated being-drawn in over thefend of the beam, under the brush, .and up over the top-Qi' the beam, while thebrush is driven in the opposite direction.

The drawing represents an arrangement of meobanisnliexnbodying" our invention, the beam or table heilig shownin-seetional elevation, and the brush -in end elevation.

a denotes a strong frame-worlnthe rear posts b of which are carried to a greater height than the front posts c, for the reception within the top rails d of a ta.- ble, e, Whichis mounted in an inclined position corresponding to the relative heights of the front and rear posts.

This'table for supportingthe skin to be treated corresponds to the support technically known to currers as the beam. To each end of itsunder surface screw-rods f are hinged, these rods extending down through the crors-beams of the framea, and

each having working upon its screw-thread two nuts,

Between each upper uut g vand the top of the beam below it is a coiled spring, i, the springs i, by their upward stress, pressing the table up intoposition, the extent of its upward movement being determined and controlled by the `nut-s h striking the bottoms of the beams, against which the stress of the springs forces Vthem.

It will readily be seen thatthetable virtually rests lupon the spiings, thus having a yielding support,

that the stress of the springs may be increased or diminished by turning the nuts g, and that the top ,0f

the table may be kept in position by the lower nuts h.

Above the table, with its shaft k-journaled in suitable pendent bracket-bearings, is a brush-cylinder, l, f

extending lengthwise of the.table, and so that its -bristles m justsweep the table-surface as the cylinder The cylinder is rotated. by any suitable power, and 4in the direction denoted by the arrow, and the skin to be treated is drawn in upon the table at the end of the machine, and belowthe brush, and is then drawn in between the brush and the table, and upward ,over the upper rail, insuch manner as to subject its whole surface to the action of the bristles, ,the manipulations ofthe Workman being guided by thejcondition of the skin andthe treatment required.

The cylinder is driven rapidly and by its actionV skins are very speedily dressed, and with-but .a small fraction of the very hard laborrequi'red to effect the saine results by hand, the operator having no brush to work, but simply having to draw through the skin in such manner as to bring its whole surface properly to the action of the bristles.

The machine is intended particularly for removing grease and dirt, and to polish morocco, upper leather,`

grain. leather, &;c., where a soft polish is wanted, and

where the use of a slicker renders the surface too.'

hard.

Te claimc The cylindrical brush m and the yielding inclined table c, when constructed and relatively arranged and combined, substantially as shown and described.
